According to a lawyer in the relevant field on the radio, this comes down to the fact the British Government gambled and got production facilities up and running while the EU messed about , if the UK government had not gambled then we’d be in the same position as the EU , so the lawyer suggested they had no claim over the supply in the UK by the fact that this stock would not have existed but for the actions of the UK government. He suggested the question in a courtroom towards the EU is why they did not get production facilities up and running and the fact they knew about the orders the UK government had placed but still delayed.
